Changing the Backlight
Your phone’s backlight has two components:
Backlight Intensity The brightness of the screen during phone activity and inactivity.
Backlight intensity has three settings:
Backlight On The brightness of the screen when there is phone activity.
Backlight Idle The brightness of the screen when there is no phone activity.
Maximum Intensity The brightness scale that applies to both Backlight On and
Backlight Idle intensities.
Backlight TimeoutThe number of seconds the phone is inactive before the backlight
dims to its Backlight Idle intensity. The backlight timeout period begins after your last key
press or the last phone event, such as an incoming call.
You can change the Backlight On intensity and the Backlight Idle intensity separately. You can
choose a high, medium, or low intensity, or turn off the backlight entirely.
When you change the Maximum Intensity, you modify the entire backlight intensity scale. For
example, if you decrease the Maximum Intensity, the low, medium, and high levels for both
Backlight On and Backlight Idle intensities decrease.
The backlight automatically turns on with any phone activity. By setting the Backlight Timeout,
you can determine how long the phone should be idle before the backlight dims to its Backlight
Idle intensity. By default, after the phone is idle for 40 seconds, the backlight dims.
To change the backlight intensity:
1 Select Settings from Home view, and select Basic > Backlight Intensity.
2 From the Backlight Intensity screen, select Backlight On Intensity.
3 From the Backlight On Intensity screen, select the intensity you want, and press Back.
The default is High.
4 From the Backlight Intensity screen, select Backlight Idle Intensity.
5 From the Backlight Idle Intensity screen, select the intensity you want, and press Back.
The default is Low.
6 From the Backlight Intensity screen, select Maximum Intensity.
7 From the Maximum Intensity screen, select Up or Down to increase or decrease the
maximum intensity the screen can display, and press Back.
To change the Backlight Timeout:
1 Select Settings from Home view, and press Basic > Backlight Timeout.
2 From the Backlight Timeout screen, enter the number of seconds the phone will be idle
before the backlight dims. The default is 40 seconds.
